Abstract

In recent years the adoption of mobile devices such as smartphones and tablets has increased dramatically. These devices allow for new 3d visualization concepts, such as the shoebox model. This concept uses perspective correction to the image on screen when the device tilted to enhance the 3d effect of the ... read more image. The field of view and the shearing factor are identified as the main parameters that determine the look of the shoebox effect. This report researches the effect of the shoebox model, on users 3d perception and experience.
To examine the effects, several user studies are performed. Each of these user studies focuses on a different task involving some form of depth perception (used as an indication of 3d perception). The participants in these studies are asked to fill out a questionnaire to gain insight in the subjective experience of users when using the concept.
The results of these studies suggest that the shoebox model has a significant positive influence on a user's depth perception. The influence of the different parameters on the depth perception is not significant. Application developers are therefore recommended to choose a value for these parameters that results in the most visually appealing effect or is most practical for its intended application.
The user reaction to the shoebox model is moderately positive. Users prefer it to the use of auto stereoscopic screens, which they noted offer a better 3d effect but are more cumbersome to use and cause fatigue of the eyes. show less
